I think you're still missing the point. A few points of wear difference here or there isn't statistically relevant and won't tell you which oil is better. Now if TBN totally depleted or oxidation is up more than 17 points from VOA, then yeah one of the oils is shot and needs to be changed.can pull off 10k miles with better numbers with AMSOIL.
I'm just trying to say that a used oil analysis isn't the tool that most people think it is. Comparing oils is not one of the applications of that tool.
